Abstract
Because it is not possible to sufficiently reduce the number base stations that start uselessly in spite of being in a low traffic state, it is not possible to lower interference between adjacent cells and power consumption sufficiently. A base station starts transmission of a control signal with predetermined power when communication between another base station and a mobile station is started and a first predetermined condition is satisfied.
